Transport Layer Security (TLS) and Secure Sockets Layer (SSL) are two cryptographic protocols used for providing secure communication over a network. The Internet Engineering Task Force (IETF) prohibited the use of SSL which led the way for TLS to succeed it. The protocols have several variations and iterations used in web browsing, email, Internet faxing, instant messaging, and voice over IP (VoIP). Websites, in particular, are known for using TLS for securing communications between their servers and web browsers. This is accomplished by TLS providing privacy and integrity to data between two communicating nodes on a network.
